JOHANNES E. ROEDER, OF INDIANAPOLIS, INDIANA.

BELLOWS.

SPECIFICATION forming part of Letters Patent No. 246,418, dated August 30, 1881.

Application filed June I, 1881.

To all whom it may concern:

Be it known that I, J OHANNES E. BOEDER, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful In1- provement in Blacksmiths Bellows, of which the following is a specification.

My invention relates to improvements in bellows in which a stationary central partition provided with an inlet-valve and dischargeopening operates in conjunction with a lower leaf hinged at the front, and provided with inlet-valves and dirt-screen and an upper pressure-leaf hinged at the rear of the bellows; and the objects of my invention are, first, to provide a blacksmiths bellows with a large windspace; second, to provide the valve-seats with woolen cloth or felt, and the valve with faces of woolen backed with pasteboard or other flexible substance; third, to provide the inlet and discharge openings of the bellows with screens for preventing the entrance or discharge of large particles of dirt, cinders, &c.;

fourth, to provide the front end of the central partition with a curved or goose-necked discharge-pipe with an adjustable end or nozzle. These objects I accomplish by the mechanism illustrated in the accompanying drawings, in which Figure l is a vertical longitudinal section of the whole device, taken at the line a: w of Fig. 2. Fig. 2 is a top view of the central partition with the pressure-leaf removed, and Fig. 3 is a perspective view of one of the woolen valves with pasteboard backing.

Similar letters refer to like parts in the sev-. eral views.

B represents the central partition, which is stationary, and provided near one end with the Valve-openings F, and near its front end with a discharge-opening, P, in which is secured one end of the curved discharge-pipe H H.

Around the valve-opening F, on the upper face of the partition B, is secured the valveseat a, made of woolen cloth, and above the valve-seat a is the woolen-cloth valve I), backed with pasteboard d, or some other flexible substance capable of holding the woolen cloth in (No model.)

position and preventing any back leakage of air from above.

The inlet-valve opening F in the wing 0 below is provided with valve seats a and valves 1) d in the same manner and of the same material. The lower side of the valve-opening F is covered with fine gauze to prevent the inflow of large particles of dirt, and the outlet-port P is also covered with wire-gauze, to prevent cinders and dirt from entering the bellows.

The central partition, B, is provided with the cross-bar K, the ends of which extend beyond the sides of the bellows, to form a support for that end of the bellows.

The upper pressure-leaf, A, has its rear end hinged at E to the cross-cleat D, thus allowing the front end to rise and fall over the discharge-openin g P.

The lower leaf, 0, is hinged at D to the front cleat, I, and the two leaves 0 A and center partition, B, are all inclosed in the leather case L, as shown.

What I claim as new, and desire to secure by Letters Patent, is-

l. The bellows-frame consisting of the central stationary partition, B, having inlet-valve opening F and discharge-opening P, and its rear upper side provided with a cleat, D, and its lower front side provided with the cleat I, combined with the pressure-leaf A, hinged to the cleat D at E, and the lower lea-f, C, hinged at I) to the cleat I, and provided with an inlet-valve, F, substantially as shown and described.

2. The valve-opening F, combined with the woolen-cloth valve-seat a, the woolen-cloth valve 1), and the pasteboard backing (1, substantial] y as shown and described.

3. The central partition, B, with valve-opening F and discharge-opening 1? into the nozzle H, said discharge-opening being covered with wire-gauze G, substantially as specified.

4. The valve consisting of the Woolen-cloth face I), backed with pasteboard 01, substantially as specified.

5. A blacksmiths bellows consisting of the stationary partition B, with inlet-valve com posed of woolen-cloth seat a and woolen-cloth vah'e b, with pasteboard backing (Z, the out- In testimony whereof I have signed mynanle let-port P, with curved nozzleH H, the pressto this specification in the presence of two lire-wing A, hinged at E to the rear cleat, D, subscribing Witnesses.
